Meyer Sound UP-4slim UltraCompact Installation Loudspeaker

Slim, aesthetically pleasing installation loudspeaker - delivers high SPL with low distortion and uniform coverage

Product Description

The Meyer Sound UP-4slim UltraCompact Installation Loudspeaker is ideally suited for applications requiring a small, slim, aesthetically pleasing cabinet that delivers high sound pressure levels with low distortion and uniform coverage. The UP-4slim offers this exceptional audio performance in a compact self-powered package with a remote power supply. As a standalone loudspeaker, the UP-4slim is appropriate for vocal reinforcement, frontfill, and under-balcony fill applications. The UP-4slim can be optionally paired with a Meyer Sound subwoofer to create a full-range system. One MM-10ACX can also power one UP-4slim.

The UP-4slim is engineered to the same award-winning standards as all Meyer Sound IntelligentDC loudspeakers. Its onboard amplification and sophisticated signal processing provide the flat frequency and phase responses for which Meyer Sound loudspeakers are known. Its drivers are designed and manufactured at the Meyer Sound factory in Berkeley, California.

The UP-4slim’s high-frequency section includes a 1-inch metal dome tweeter on a constant-directivity, high-frequency horn. The low/ mid-frequency section includes two 4-inch cone transducers that work in parallel at low frequencies to deliver a combined acoustic output. One of the drivers rolls off at higher frequencies to maintain constant directivity in the crossover region.

With a smooth and consistent 100° coverage, fewer loudspeakers can cover a larger area, reducing system cost while maintaining the highest sound quality. With IntelligentDC technology, the UP-4slim receives DC power and balanced audio from a single Phoenix™ 5-pin connector. Powering the loudspeakers from a Meyer Sound IntelligentDC external power supply eliminates the need for wiring conduits while still preserving the advantages of self-powered systems.

The Meyer Sound IntelligentDC power supplies distribute DC power and balanced audio to UP-4slim loudspeakers or other Meyer Sound IntelligentDC loudspeakers. The UP-4slim’s amplifier and signal processing circuits store DC power and tolerate voltage drops, thereby accommodating light-gauge cables and lengthy cable runs. Composite multiconductor cables, such as Belden® 1502 or equivalent, can deliver both DC power and balanced audio to loudspeakers at cable lengths up to 150 feet with just 1 dB of loss in peak SPL using 18 AWG wire for power. Longer cable lengths are possible with heavier gauge wires. The 2-channel MPS-482HP power supply is ideal for applications requiring a small channel count or the capability for mounting the supply remotely on a wall or ceiling, while the 8-channel MPS-488HP is ideal for larger installations. In addition, the MPS-488HP can also connect to Meyer Sound’s RMS remote monitoring system.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
